We study the strain and elemental distribution in La2/3
(LSMO) doped with ZrO2
using analytical TEM techniques. ZrO2
forms non-magnetic nanoparticles that introduce anomalous magnetic anisotropy and modifications to the electric transport properties of the LSMO thin film. Using electron energy-loss spectroscopy (EELS) in a probe-aberration-corrected JEOL JEM-ARM200CF, the atomic resolution elemental distribution of La, Sr, Mn, Zr and O, and the Mn valence state variation at the interface between LSMO and ZrO2 are observed.
